It's really hard if you only can online 2 hours a day. But i think if you have 1 or 2 BTC you can start with trading

you can earn really quick but be carefull before you start. It's not safe

I think you didn't read his post clearly, he has clearly said that he is looking to earn bitcoins without making an investment as he don't have an investment to make so how can you say that if you have 1 or 2 btc then start trading as if he would be having that high amount then why he would have asked for the methods of earning bitcoins and he can also spare only 2 hours per day so in that case its very difficult to find methods of earning bitcoins.
to me i think the only way through which we can make more than one bitcoin is trading, through trading we can really make a good profit may be much more than 1 0r 2 bitcoins. but we must have good trading experience.
